Currently i run pubsweet app by running pubsweet server to start backend and frontend app. Is there a way to separate back-end and front-end into two different services ?
Yes, there is! If you’re using the latest PubSweet CLI (this was added in pubsweet 5.1.0 (https://gitlab.coko.foundation/pubsweet/pubsweet/blob/master/packages/cli/CHANGELOG.md#510-2019-08-30) you can use:
pubsweet start:client
and
pubsweet start:server
